iOS app launch failure

[pgte]

I followed the install instructions to the best of my knowledge and, when running the yarn iOS command, I get the following error:

error: /Users/pedroteixeira/projects/rakning-c19-app/ios/Pods/Target Support Files/Pods-Rakning/Pods-Rakning.debug.xcconfig

Here is the full output:

→ yarn ios
yarn run v1.21.1
$ react-native run-ios
error React Native CLI uses autolinking for native dependencies, but the following modules are linked manually:
  - @react-native-community/async-storage (to unlink run: "react-native unlink @react-native-community/async-storage")
  - react-native-splash-screen (to unlink run: "react-native unlink react-native-splash-screen")
This is likely happening when upgrading React Native from below 0.60 to 0.60 or above. Going forward, you can unlink this dependency via "react-native unlink <dependency>" and it will be included in your app automatically. If a library isn't compatible with autolinking, disregard this message and notify the library maintainers.
Read more about autolinking: https://github.com/react-native-community/cli/blob/master/docs/autolinking.md

Strange. Can you try opening ios/Rakning.xcworkspace in XCode and running the project in a simulator?

You might see more detailed errors there?

Also, if this error is accurate it might indicate an error installing pods. Can you run yarn prepare and check if there are any warnings or errors there?

@eirikurn After doing yarn prepare(which yielded no errors), build started working.
Thanks for the help!

This happened to me also and lost a few hours trying to figure it out. Maybe we could consider adding it to the README?
